[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of components such as beams, steel columns and steel trusses made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts and rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

After adjusting the distance, the spring contracts so that the upper fixing plate and the lower fixing plate can be tightly attached to the steel structure joint, which is convenient for the subsequent fixed connection of the fixing bolts I and II.

[0004] However, at the joints of the steel structures, the reinforced structure usually needs to be fixed by bolts and rivets, which requires drilling holes on the surface of the steel structure, resulting in a decrease in the structural strength of the steel structure. Utility Model Content

[0024] In this embodiment, the height of the support seat 7 is adjusted so that the support seat 7 abuts against the inner wall of the I-beam 1 . At this time, the support seat 7 is connected to the cover plate 6 to fix one end of the I-beam 1 .

[0025] like Figure 2 and Figure 3As shown in the figure, for the convenience of adjusting the height of the support base 7, a lifting sleeve 12 is rotatably installed in the moving base 10. Lifting cavities 14 are provided at both ends inside the lifting sleeve 12. Lifting screws 13 are threadedly connected inside both of the two lifting cavities 14, and the lifting screws 13 are fixedly connected to the support base 7.

[0026] In this embodiment, manually pull the two support bases 7, and by rotating the lifting sleeve 12, under the threaded connection between the lifting cavity 14 and the lifting screw 13, the lifting of the support base 7 is realized, so that the support base 7 abuts against the inner wall of the I-beam 1, thereby realizing the support of the I-beam 1.

[0027] As Figure 1 、 Figure 2 and Figure 4 shown, for the convenience of adjusting the position of the moving base 10, a threaded sleeve 11 is rotatably installed inside the moving base 10. The threaded sleeve 11 is threadedly connected to the lead screw 9, and one end of the threaded sleeve 11 penetrates through the moving base 10 to form a driving shaft sleeve.
